Abstract

Des systèmes et des procédés qui utilisent directement une grille d'objet basée sur une atténuation d'image, utilisent une grille de source pour améliorer l'imagerie de la grille d'objet à l'aide d'une source polychromatique à haute énergie, et utilisent une grille de détecteur ayant des réseaux orientés sensiblement orthogonalement à celui de la grille d'objet, peuvent remédier à des artéfacts et des effets de durcissement de faisceau qui limitent la qualité et la puissance discriminatoire d'une imagerie par rayons x à haute énergie qui comprend un contraste de phase.
